SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indicator
system will remind you that it is time to take your
vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent short-trips,
trailer tow, extremely hot or cold ambient
temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is
displayed. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for fleet
customers.
Once A Month Or Before A Long Trip:

Check engine oil level.

Check windshield washer fluid level.

Check the tire inflation pressures and look for
unusual wear or damage.

Check the fluid levels of the coolant reservoir,
brake master cylinder and fill as needed.

Check function of all interior and exterior lights.
